Pretty old stuff compared to the latest boutique pedals but still unique and rare. I guess nobody can be surprised by chorus+vibrato+compressor, but this pedal, the way these features mixed and tuned here - its just killing me. This is the real inspiring effect, cuz no matter what did you played before it but once you hit it - you just want to strum some slow stuff with chords. Basically it throws you back to the 80-90s. Joke, lets look serious at it. THe controls are not so obvious as they seem. The "tone" control dials the compression-limiting of your signal , volume and tone as well. So the volume control sits here to compensate the tone knob I would say. "Comp lo-fi" knob - we can call it the soul of the pedal. From the 7 to 10 o'clock you got nothing but compression, the from the 10 to 1.5 o'clock the sweet and soft chorus mixes in, and later from the 1.5 to 5 o'clock you are getting vibrato effect which detunes you guitar in a very cool way, also it adds some white hiss. Got to mention - you will always have you signal compressed and limited even if you go full clockwise. So this knobs basically adds chorus and vibrato to compression. The "depth" dials the depth of chorus and vibrato, the funny thing that "speed" control dials the depth too, so setting this pedal up may be a bit tricky. That little toggle switch changes the waveform, the third mode gives you and effect of stuttering gramophone, great stuff for finish tracks. It should be used with a clean amp or after your dirt pedals. I dig this pedal these days very much, MacDemarco in a box lol.
